The latest spate of military attacks on Iran’s nuclear facilities has propelled the region into a new era of uncertainty, with world powers holding their breath for Tehran, Washington, and Jerusalem’s next steps. The assaults represent a dramatic new phase after years of inconclusive diplomacy, the collapse of the 2015 nuclear accord (JCPOA), and a series of repeated crises over Iran’s nuclear intentions.

Iran’s Most Guarded Sites Under Fire

The target of the coordinated attack was three of Iran’s most critical nuclear facilities: Fordow, Natanz, and Isfahan. All three play a critical role in Iran’s nuclear program—and all present different challenges to bombers. Fordow, particularly, is notable for being deep beneath a mountain outside Qom, and it is famously hard to destroy. Radio Free Europe/Radio Liberty analysts report that Fordow is so heavily buried it’s inaccessible to Israel’s conventional forces, necessitating special American bunker-busting bombs.

America’s Bunker-Buster Enters the Scene

To target Fordow, the United States used the GBU-57A/B Massive Ordnance Penetrator, a 13,600-kilogram penetrator designed to blast through deeply buried targets. Dropped only by the B-2 Spirit stealth bomber, which Israel does not possess, this bomb is the culmination of bunker-busting technology. Even so, analysts caution that even the MOP will likely take more than one hit to succeed, and the precise design of Fordow remains an intelligence enigma.

Natanz and Isfahan Damage: A Mixed Picture

While not as deeply buried as Fordow, both Natanz and Isfahan are sufficiently hardened to reduce the impact of even sophisticated weapons. U.S. officials admit that parts of these sites—and stocks of enriched uranium—have survived intact. Tomahawk missiles hit surface facilities at Isfahan, with GBU-57s deployed in Natanz. NBC News quotes U.S. estimates that only Fordow was largely eliminated, and perhaps brought operations there to a two-year halt. The other facilities, though damaged, might be operational within months.

White House Claims Victory, Experts Sound Warning

The Biden administration has cheered the operation—”Operation Midnight Hammer” for short—as a grand triumph. White House press secretary Anna Kelly announced that Iran’s nuclear facilities had been “destroyed.” However, intelligence reports paint a more mixed picture. Fordow was heavily damaged, but most of the uranium in Isfahan and Fordow was not eliminated—merely buried deeper. U.S. and Israeli officials concur that the raids were a significant setback, but Iran’s nuclear program is by no means dead. The warning is explicit: if Iran attempts to retaliate, more strikes will ensue.

Even the Best Weapons Have Limits

The military challenges of bombing these facilities are significant. Defense analyst Heather Williams pointed out that although satellite photos reveal extensive damage at Fordow, the facility’s depth renders it hard to fully destroy. The Pentagon originally planned a more extensive campaign against Iran’s air defenses and other capabilities, but was deterred by fears of civilian casualties and a lengthy war.

Environmental Fallout: Not as Bad as Feared

There have been questions raised about the environmental damage, but nuclear specialists informed ABC News that the danger is fairly minimal. Compared to nuclear weapons, uranium enrichment plants don’t generate large-scale radioactive fallout. Any uranium hexafluoride gas released, though hazardous, is chemically toxic—rather than radiologically—and dissipates readily. A catastrophic event such as Chernobyl is not thought probable, particularly as Iran’s reactors were not struck.

The Death of the Nuclear Deal

The attacks also highlight the collapse of the JCPOA. Initially touted as a historic accord constraining Iran’s nuclear ambitions in return for sanctions relief, the accord dissolved after the U.S. pullout in 2018. Iran then restarted enrichment and reduced international scrutiny. The Council on Foreign Relations succinctly declared that the pact is now “effectively defunct” with Iran’s breakout time to build a bomb reduced to a few months.

Iran’s Next Step and the Risk of Retaliation

Its nuclear facilities damaged and its air defenses shattered, Iran is now sitting in a precarious position. The risk of future attacks hangs over whatever rebuilding occurs. But the scenario is still volatile—Tehran is still able to strike back at U.S. or Israeli targets throughout the region, threatening wider war.

War Games Beneath the Surface

This whole campaign is now a risky game of military brinkmanship—one that combines high-tech weapons with the old-fashioned approach of burying vital infrastructure underground. The message from Washington and Jerusalem is clear: there is no room for ambiguity anymore. Whatever Iran does to advance the building of a nuclear bomb will be met with firm action. But as history has so frequently demonstrated, even the strongest bunkers can’t provide certainty of protection.
